Spark plug important element by proper selection of engine, this efficiency depends on the details of the entire engine.

Note

Spark plug special design with a noise resistor. The resistor is made of composite materials to ensure high performance and reliability. The gap between the electrodes of standard thread length-19 mm. Candle is made of aluminosilicate materials, reducing the level of pollution.

Construction features

Resistor-fluctuating energy in time of creating sparks, form the radio frequency interference. Data interference affect power stations, radio transmitters and electronic control units, including engine control unit. Usually the resistor has a monolithic structure made of graphite and glass, his task is to organize the Central electrode voltage inside the candles. Because the resistor has a resistance, candles not equipped them with more powerful spark, as reduced energy loss in passage through the Central electrode. For this reason, most sports and racing engines use candles without a resistor. Note, however, that if the manufacturer setting of candles with resistor, then the installation can adversely without candles affect the operation of this engine.
